When you have finished this page, try the Chemical and Physical Changes Quiz. There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is.In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed. For example, if a piece of paper is cut up into small pieces it still is paper.f the same piece of paper is burned, it is broken up into different substances that are not paper. Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all.
